First, check the battery. It might not be the actual problem, but you can't test anything else with a bad battery. Brands and stores don't matter. There's three companies that make lead acid batteries in the US. Johnson Controls, Exide and DEKA. Even most dealership replacements will be from one of these three. Usually the best bet is the most capacity and best warranty. Walmart and Costco both satisfy this. If the battery is bad and was bought at Costco 2 years ago, you should be able to get a replacement. (36 month free replacement warranty)

To easily test the battery, fully charge the battery, and with the car off measure the battery voltage. Take another reading while it's in the crank position, and a last while running. Fully charged off should be about 12.6V, cranking should be about 11.5V and definitely not lower than 11, and running over 13.8V.

Next time it happens, tap on the starter a few times with a hammer and see if anything changes. If it cranks right afterwards it's likely the starter solenoid sticking. You'll need to replace the starter at that point.

If that doesn't change anything, check the voltage drop on your cables. Put your multimeter on volts and place one lead on the positive battery post, and then the other at the study on the starter solenoid that the battery cable connects to. Have someone crank the starter. Your reading shouldn't be much more than about 0.3V.

Repeat with one meter lead on the negative battery post, and another on a clean ground around the starter. A transmission bellhousing bolt head would work well. Also shouldn't be much more than about 0.3V.
